COVER PANEL

The invention relates to a sheet-like structure that can be drawn existing cover panels, particularly but not exclusively on metal cover panels so formed are that they simulate the appearance of building materials or the like and thereby a plurality of adjacent ones have surfaces lying in diverging planes. For example, horizontal elongated metal cover panels are designed so that that they resemble a series of cracked wooden shingles. The invention also relates to a method for Manufacture of these tablets.

For the purpose of a more uniform presentation, the invention is described below, in particular with reference to aluminum

809833/11

cover panels, where the term "aluminum" encompasses aluminum metal and its alloys, and that the term "cover panels" includes panels which can be used for both the installation on roofs as well as on walls are suitable.

Roll formed aluminum cover panels are widely used to cover the exterior walls of buildings or to disguise. Such panels can be stacked in parallel, overhanging and locked relationship be attached. Each panel has an elongated bead or flange formed along its upper edge elongated lip and an elongated inwardly curved channel flange formed along the lower edge. The panels can be attached to a wall with their upper edge by means of nails or in some other way, whereby the top edge is substantially flush with the wall and the gutter flange of each panel locks immediately below it is to secure the lower board edge against dislocation, while the lower edge of the board in a way is kept away from the fact that the appearance of wooden roof shingles is simulated. An advantage of the fact of this Type is that they can be of relatively great length (e.g., 3.7 meters or more in a horizontal direction stretching with an exposed vertical extent of 20.5 cm or 25.5 cm) as this is for convenience and is desirable for ease of use and installation.

While the described shingle appearance of these panels is satisfactory for many installations it is often desirable “other aesthetic or design effects to create an outer wall covering that has the functional advantages of an aluminum or Make use of cladding made of other sheet or sheet material. In particular, it often is

it is desirable in such a cladding to simulate the appearance of such wood shingles that are conventional as so-called cracked shingles (shakes), in which, for example, by weather or by Sandblasting between the grain, the soft wood components are eroded out and thus a raised pattern arises. Heretofore, however, the proposed designs of clapboard simulating metal cover panels have brought about difficult shape problems, because of which it was essentially not possible, a close resemblance to the true surface appearance a number of the aforementioned wood shingles. In addition, as a result of the special Shape problems limited or restricted the lengths of such clapboard-like panels: i.e. it was not possible to obtain a satisfactory sheet metal product which can acceptably have a number of paneled Hoiz shingles simulated and in terms of length with the conventional metal panels of the type described above are comparable. Thus, although long horizontal metal cover panels have been considerably more such by the installers Covering panels are preferred, not long (i.e. 2.5 m or more) to achieve the above results in horizontal extension) clapboard-like metal panels have been available so far.

In connection with the explanation of what occurs when trying to reach long clapboard-like metal panels Difficulties can be found in the exposed surfaces of a number of wooden clapboards usually in downwardly diverging planes. This feature can be applied to an aluminum panel are simulated by alternately forming first and second shingle-like areas in this, which each extending across the width of the panel, with their respective faces in downwardly diverging planes lie. However, since the divergence of this clapboard-like

809833/1 118

Areas from a common plane at the bottom of the panel is considerably larger than in the upper area of the same _P , the bottom edge of the panel is accumulated, ie shortened in terms of length relative to the upper panel area. This difference in length can be tolerated if the panel is sufficiently short in terms of its horizontal extension. However, with large lengths of the panels (compared to the lengths of conventional clapboard-like aluminum cladding panels) as desired by the installers, the inequality in length between the bottom and top of the panel is so great that an unacceptable bowing, sagging and / or other deformations of the panel occur.

The invention, while eliminating the aforementioned disadvantages, creates one made of an elongated, drawable sheet-like structure manufactured covering board simulating a horizontal row of wooden shingles, with an elongated one on top of it Support surface attachable and lying on this surface upper edge area, an inwardly elongated lower edge portion which forms a flange to support the lower portion of the panel which the lower Areas of the panel outwardly spaced from the support surface and with a continuous between the upper and lower edge area for the full horizontal length of the panel leading outward from the upper edge area is inclined and has a multitude of raised clapboard-like areas and a multitude of indented areas is provided with shingle-like areas which are arranged alternately along the length of the web, with web areas extending between the adjacent raised and indented areas, around side edge areas to simulate the simulated raised clapboard.

809833/111!

In preferred arrangements the raised ones become clapboard-like Areas of the board with straight side edges formed, which are all parallel to each other (and transversely to the longitudinal edges of the panel), while each indented clapboard-like area with straight Side edges are formed which diverge upwards in such a way that each indented area is larger at the head end is than on the ground. In this way, each side edge of an indented area and the adjacent side edge of the adjacent raised area upwards, i.e. towards the upper edge of the panel, and form between sloping areas. The upward convergence of the two last-mentioned edges forms the upward tapering of the sloping area, the inclination of the same (relative to the planes the clapboard-like areas) progressively in an upward direction in connection with the convergence of this area forming lateral edges grows.

The panel may be preformed with an elongated, inwardly protruding flange which extends along the bottom edge the board runs. In addition, the panel may have a pre-formed outwardly protruding elongated lip, which runs along the top of the panel for interlocking with the bottom edge flange of another Blackboard. This flange and this lip can be formed or manufactured in the same way as the existing ones clapboard-like aluminum cover panels. The upper edge of the board protrudes from the lip and is aligned so that it is substantially flush with a wall or support surface on which the panel is to be fixed.

The shingle-like and sloping areas can work together to create a visual impact or an optical illusion diverging downwards

Create shingle surfaces; that is, the surfaces of the adjacent raised and depressed shingle-like Areas appear to be in downward diverging planes, although these areas are actually in parallel planes arranged at a distance from one another lie. So the board formed in this way actually represents the appearance of a series of cracked wooden shingles, the surfaces of which diverge in downward direction Levels lie. Since the surfaces of the adjacent clapboard-like areas of the board lie in parallel planes, while the sloping areas between these taper upwards and upwards with respect to them As the slope increases, there is no greater accumulation of material at the bottom edge of the board than in the upper area the blackboard. Thus, the length of the panel at the bottom edge is not reduced relative to the top of the panel. Indeed becomes a slightly larger horizontal for the amount of deformation caused in the upper area of the panel Material length required than is necessary for the amount of deformation in the lower area of the panel. However, the elongated lip formed in the upper edge area of the panel has a dimensional stabilizing effect adapts this requirement by stretching metal in the top of the panel during the deformation process. Consequently, the top and bottom edges of the panel keep substantially the same length so that the panel is as long as conventional aluminum cover panels currently in use (e.g., 2.45 m to 3.70 m or even more in a horizontal extension with a width of 30.5 cm or less) without the occurrence of harmful deflections or bulges or other harmful deformations.

According to a further preferred feature of the invention, with regard to supporting an effective

809833/1118

fully simulates the appearance of cracked wood shingles the bottom flange of the panel are deformed (associated with the molding process or the formation of the clapboard-like areas) so that the bottom edges of the indented clapboard-like areas follow a little protrude below the bottom edges of the raised clapboard-like areas. The resulting irregular The bottom line of the board creates a shadow line when a row of boards is arranged on a wall and be irradiated by sunlight. This shadow line is similar to the irregular and uneven shadow line a row of wooden shingles.

The elongated upper edge area of the panel above the lip is preferably corrugated transversely to avoid dimensional shifts to compensate in the main area of the board, which in this by the formation of the shingle-like Areas have arisen. This corrugation of the upper edge works together with the other previously described features of the invention, to maintain the desired dimensional stability and to keep the board free from harmful deformation.

In preferred methods for producing a cover or cladding panel of the type described above, it is that an initially flat metal strip is subjected to successive deformation steps, one elongated upper lip and an elongated bottom flange can be formed. This is followed by cold deformation of the area of the Strip between the lip and the flange in a multitude of alternating raised and indented shingles Areas with inclined areas in between, as already described above. Thereafter, the upper edge of the strip is preferably corrugated above the lip. The strip can be on conventional Painted or otherwise in front of the template

are going to be provided with a protective layer. Additionally and again before following the aforementioned deforming steps, the strip can if so desired will be embossed with a vertical or other wood grain pattern. It is understandable that the term "vertical" refers to the direction across the length of the strip, i.e. when it is fully assembled Panel present vertical direction.

The steps of deforming the lip and flange can be accomplished by conventional roll forming operations take place, as it was previously used to form similar parts on conventional metal cover panels became. The step for deforming the clapboard-like and sloping areas can be as well be effected by roll forming, for example by placing a suitably constructed roll stand in series is used with other conventional roll stands in a roll forming line, which sequentially all the forming operations carries out the previously described type .. The metal can lead to this road as a continuous strip conveyed and then cut into the desired sheet lengths at a suitable point »

Preferably, the panel has an area ratio (i.e., a ratio of horizontal extension or length to vertical extension or width) of at least about 7s1. The panels are preferably 305 cm or more long and about 8 to about 16 inches wide exposed = These boards simulate when they are mounted on a wall in overlapping parallel relationship one on top of the other in the surface design the appearance of a series of wooden shingles or cracked wooden shingles (shakes), whereby each row of shingles overlaps or protrudes over the upper area of the next following row and within individual clapboard or groups of clapboards in each row

With reference to Figures 1 to 5, the invention relates to a horizontal cover panel made from a strip of aluminum was produced. This aluminum strip was at least on its outer surface with a or several protective layers of paint. Thus, in Fig. 1, one is horizontally elongated formed aluminum cover panel 10 shown, which is of sufficient thickness for the self-maintenance of their shape and is provided with an upper edge 11 and a lower edge 12. The board can after roll forming have a vertical dimension of approximately 23 cm from the top to the bottom. In a horizontal extension can the board have a length of 3.6 m and more.

The upper edge 11 is provided with a longitudinal edge 14, which is substantially flush with an exterior wall when the panel is installed. For example through this longitudinal edge 14 can be driven nails or other fastening means through holes 14a, which for Attach the board to the wall spaced along the length of the board. Direct below the edge 14 is the edge 11 with one to the outside and downwardly protruding elongated lip 16, which extends over the entire length of the board. The lower edge 12 is according to the illustration bent inwards and then upwards again to form an inwardly protruding elongated channel flange 18 form, which also extends over the entire length of the panel. The main extent of the panel between the The upper and lower edges of the same consist of a continuous web 2O, and have an outwardly directed main surface and is designed according to the following description. The terms "outside" and "inside" are used below used to the effect that the direction away from the wall or towards the wall is meant on which the Panel is mounted. The terms "above" and "below" are used

- 15 809833/1118

used with reference to the orientation of the board when attached to a wall.

When an array of panels are attached to an exterior wall by placing one above the other in parallel, each panel runs horizontally and by fastening each panel with the upper edge 11 flush with the wall on this is, the gutter flange 18 of each panel overlaps the lip 16 the panel immediately below and is locked to it. This way, each panel will be along the top and lower edges held against displacement. The bottom of each panel is through the flange 18 both at a distance from the wall and at a distance from the upper area of the immediately adjacent panel. The amount such a distance is determined by the depth (transverse to the horizontal orientation) of the flange. To this Each board falls downwards and outwards from the upper edge to the lower edge of the same.

The web 20 consists of a plurality of raised clapboard-like ones Areas 22 and a plurality of indented areas 24, which alternate one after the other along the length of the panel and are separated by narrow, vertically oriented sloping areas 26. Everyone Area 22 and 24 runs vertically from the top of the panel (just below lip 16) to the bottom 12 of the panel and has a substantially planar outwardly directed major surface. The sublime! and indented web areas 22 and 24 are of a width (i.e., horizontal extent measured along the length of the panel) of one or simulate more conventional cracked wood shingles, although the raised and indented areas are both preferred have a random width, with some of the indented areas being at least the width of some of the raised areas Areas are the same.

- 16 -

809833/1118

As can best be seen from FIG. 3, all of the raised, shingle-simulating areas 22 are very particularly formed lying with their outwardly directed main surfaces in a first common plane, while all indented shingle-simulating areas 24 with their outwardly directed main surfaces in a second common Are designed lying flat, i.e. parallel and at a distance inward from the plane of the areas 22. On this In this way, the indented areas 24 are offset inward from the raised areas 22 by an amount that which from the uppermost extent of these shingle-like areas immediately below the lip 16 to the lower Edge of the panel is essentially constant. The inclined track areas 26 form such track areas, which are bent obliquely (obliquely to the planes of the parts 22 and 24) in order to be offset relative to the areas 22 Areas 24 to adapt to one another or to create a transition between these parts.

The side edges of the raised clapboard-like areas

22 are formed by relatively sharp straight, vertical bending edges 23, while the side edges of the indented Shingle-like areas 24 are formed by relatively sharp straight bending edges 25. As As best seen in Figure 2, the side edges or bending edges 25 diverge on opposite sides of each indented area 24 upwards so that the area 24 is slightly wider at the top than at the bottom. Since the side the raised areas 22 forming side edges or bending edges

23 all run vertically, these are arranged parallel to one another, so that each raised area goes from top to bottom has a uniform width.

Each obliquely or inclined area 26 is one of the raised shingle-like areas between a side edge 23

- 17 -

809833/1 118

Areas 22 and the adjacent side edge 2 5 of the adjacent imprinted clapboard-like area 2 4 formed. Thanks to the previously described divergence of the edges

25 upwards and the vertical alignment of the edges 23, those formed by the edges 23 and 25 diverge obliquely areas running upwards (when seen projected into a plane) which are parallel to the surfaces is even in the clapboard-like areas. Therefore, the inclined area 2 6 tapers between the edges 23 and 2 5 upwards (seen in the same plane).

Since the edges 23 and 2 5 forming each inclined area 26 are each arranged at a distance from one another parallel planes, it follows from the upward convergence seen in the projection that the Inclination of the surface of the inclined area 26 increases progressively upwards. This means that in the lower area the slab the inclination of the area 26 relative to the surface planes of the areas 22 and 24 for comparison is gradual or gradual. In the upper part of the table, however, this slope is considerably steeper, as shown Fig. 5 is clearly visible. In this Fig. 5, a section 5A-5A (see Fig. 2) in the lower region of the panel is through unbroken lines Lines and a section 5B-5B in the upper part of the panel shown by broken lines. The inclination the surface 26 in the lower area is more gradual than the slope 26 'in the upper area, in accordance with FIG progressive apparent convergence of the edge 25 with the edge 23 (the position of the edges 25 in the upper part of the Table is in Fig. 5 by point 25 '). It can be understood that the change in inclination of the area shown in FIG

26 is uniform and continuous from the bottom of the edge of the panel to the top edge of area 26.

It was found that the above-described design the panel track 20 including the raised and

809833/1118 ¹⁸

280668Q

indented clapboard-like areas and those in between inclined areas located a visual effect or an optical impression of a downward directed divergence of the surface planes of areas 22 and 24, i.e. that the appearance of a series of cracked wood shingles or is simulated by wood shingles with a raised grain, although the planes of areas 22 and 24 are actually parallel rather than diverging. The described Arrangement of the shaped web 2o does not require a greater metal surface length than in the lower region of the panel in the upper area of the table, which would be the case if the planes of areas 22 and 24 diverge towards the bottom would. From this it follows that the bottom edge of the panel is not piled up relative to the top of the panel is shortened so that buckling or other harmful deformations are avoided. Taking into account Fig. it can be seen that the metal surface length required at the top of the formed web is greater than in the lower region of the formed path, since the distance from point 23 to point 25 when it is along the interrupted Line 26 'measured is greater than the same distance measured along the solid line 26. However has the lip 16 (which is formed in the panel before the shingle-like areas are formed like this will be explained further below) a dimensional stabilizing effect such that that for the upper range the greater metal length required for the web is more likely to be created in connection with the forming process by stretching, than by piling up or shortening the top of the panel.

Another feature of the invention is to enhance the simulation of the appearance of wooden shingles the areas of the panel bottom edge 12 that coincide with the indented areas 24 are shaped downwards,

809833/1118 - 19 -

as indicated at 29 (FIGS. 2 and 3), so that these areas protrude further down than those with the raised ones Band areas 22 coinciding bottom edge areas 27. In other words, this means that the indented areas as a result of this deformation of the panel bottom edge the locations of the indented areas are formed so that they protrude a little further down than the raised areas, creating an irregular lower boundary line that is similar to the line, the one found on a number of cracked wooden shingles and which then creates a shadow line similar to that created by a row of wood shingles if an arrangement of panels on a wall (i.e. in the manner shown in Fig. 6) is attached and is irradiated by the sunlight. As can also be seen from FIG is, is in accordance with the main surface design a clapboard wall, the distance between the main planes of the adjacent areas 22 and 24 is a small fraction the depth of the flange 18 when measured along a line transverse to these planes.

The method according to the invention for making a panel shown in Fig. 1 will be described with reference to Figs understandable, which show the successive process steps. The starting material for the process can consist of a flat strip 10 'of aluminum, which is for example pre-painted on its outer surface' and is of indefinite length, for example this material in the form of a spiral or a reel is. First, the longitudinal edges of this strip are deformed as shown in Fig. 8 to the upper To produce the lip 16 and the bottom flange 18, then, as shown in FIG. 9, the raised and depressed Areas 22 and 24 and the intermediate sloping areas 2 6 formed in the panel web 2o,

- 20 -

809833/1 1 18

the downward projections 29 being depressed each Area 24 can be produced by deforming the panel base edge 12 when the indented areas 24 be shaped. Finally, as can be seen from Fig. 10, the upper longitudinal edge 14 of the panel is above the lip 16 is corrugated transversely to the previous one To compensate deformations of the band 2o occurred dimensional changes. These corrugations are shown in FIG Cross-section shown.

A vertical or other wood grain pattern may be impressed in the strip 10 'prior to that shown in Figures 8-10 Deformations are carried out to give the shingle-like areas 22 and 24 of the finished panel the appearance of a to give natural wood grain. A product with an indented or embossed vertical wood grain pattern is shown in FIGS. From Fig. 14 is a diagonal aligned embossed grain pattern shown. The embossing causes a surface deformation of the strip, such as this is indicated at 30 in FIGS. However that is Depth of deformation in relation to the distance between the planes of the raised and indented shingle-like areas 22 and 24 low.

While the shingle-like and inclined areas are formed in the panel by various cold working techniques, it is particularly considered suitable _for producing the shingle-like design by roll forming. Indeed, a significant specific advantage of the shingle-like structure of the panel of FIG. 1 is that it can be easily formed by a suitably designed roll stand, which roll stand can be incorporated into an otherwise conventional roll forming line, in through all the deformation steps for the final sheet from the raw strip 10 'one after the other.

leads can be.

15 to 19 show a roll forming machine with which the method steps shown in FIGS. 8-10 can be carried out, which in particular comprise method steps for forming the shingle-like and inclined regions in the sheet web. 15 schematically shows a roll forming line 32 which has successive roll stands 34, 36, 38, 40, 42 and 44, through which the raw strip 10 ^{1 is} successively advanced in the direction of arrow 46. Each roll stand comprises an upper roll and a lower roll between which the strip is fed. The successive roll stands process the strip and form the longitudinal flange and the lip, the shingle-like and sloping areas and the upper edge corrugations in it. For example, the strip is cut into panels of the desired length in a conventional manner at a suitable point in or at the end of the line.

In particular, in the line 32, the roll stand 42 (shown in FIGS. 16 to 18) is intended to produce the sheet web 2o to reshape into the shingle-like structure of the type described above. This roll stand 42 comprises an upper cylindrical Roller 48 and a lower cylindrical roller 50 connected to one another by means of a suitable conventional gear mechanism are driven. In the surface of the roller 48 a pair of inserts 52 and 54 are fixed, the relatively extended Have surfaces that are spaced radially outwardly from, but concentric with, the surface of the roller 48 lies. These inserts are unevenly spaced from one another and have different ones in the circumferential direction width measured by the roller. This distance and this width corresponds to the desired width and the desired Distance between the indented clapboard-like areas to be formed in the panel. Appropriately,

In the lower roller 50, four narrow inserts 56, 58, 60 and 62 to cooperate with the edges of the inserts 52 and 54 of the top roll in the molding process. In the lower roller 50 is formed in the vicinity of the right end thereof (see Fig. 3 6) a circumferential groove 64 for Receiving and adapting to the previously formed flange 18 of the panel. The left end of the upper roller 48 is similar the illustration in Fig. 16 offset from the left end of the roller 50, specifically for adaptation to the preformed lip 16 of the advanced between the rollers Blackboard.

This mandrel cooperates with rollers 48 and 48 to prevent excessive and undesired deformation of the Flange 18 to prevent the strip through the Rolling arrives, with a limited deformation of the flange 18 allowed as described below will. It is preferred that the strip advancing towards the roll stand 42 have the surface of the web 20 in is on a single level. If the strip is between the
